Wildcat Freedom Series 1 Phase Tier 4F Diesel Generator (10kW or 15kW)

Prime rated, liquid cooled, built to run. Clean power for homes, ranches, and remote sites.

When outages stop being “rare” and start being “normal,” you need a generator that is designed for continuous work, not occasional weekend use. The Wildcat Freedom Series is a fully redesigned 1 phase diesel generator line built for superior durability, long runtimes, and premium power quality that protects modern electronics.

Choose 10kW or 15kW, both in 120/240V single phase, with a commercial enclosure and included fuel tank. Hand assembled in Wichita, Kansas, and backed by a 3 year / 5,000 hour limited warranty for on grid and off grid use.

Why homeowners and contractors choose Freedom

It runs like a real power plant, not a loud emergency tool

Freedom is built around an extreme duty, liquid cooled KOEL Tier 4F diesel engine at 1800 RPM. Lower RPM means better fuel efficiency and less wear than high RPM air cooled units. Liquid cooling keeps temps stable during long runs and tough weather.

It is safe for modern electronics

Today’s homes and job sites are packed with sensitive electronics. The Freedom Series delivers clean, stable output with:

• < 3.5% THD (total harmonic distortion)
• ±1.0% voltage regulation from no load to full load
• Automatic Voltage Regulation (R120 AVR)

That means your router, security system, computers, TVs, and modern furnace controls are far less likely to get hammered by dirty power.

It is built for harsh climates

Freedom’s Level II commercial enclosure is corrosion resistant and designed for harsh coastal and extreme climates, plus improved service access and sound attenuation. This is the kind of enclosure you want when the generator lives outside year round.

What it powers in real life (not just on paper)

At home and on the ranch

The Freedom Series is ideal for essential circuits and whole-home style backup designs (when properly sized and installed):

• Refrigerator and freezer
• Lights and outlets
• Modem, router, Starlink and network gear
• Security system and cameras
• TVs, computers, phone chargers
• Furnace blower and basic heating controls
• Window AC units and many mini split scenarios (load dependent)

At work sites and light commercial

Clean, stable power for:

• Office phones, computers, and fax machines
• Tools and equipment on remote job sites
• Break rooms, lighting, and site trailers
• Farm loads like fans, small pumps, and general utility power

If you are powering a mix of motors and electronics, Freedom’s low THD and tight regulation matters.

Built for long runtime and hands off operation

Prime power rated

Freedom is built to run for extended periods. It is not a “one storm per year” generator. It is designed for serious duty cycles in:

• Residential and light commercial
• Off grid and micro grid
• Disaster relief
• Military and first responder
• Remote locations

Fuel tank included, with 12 hour capacity option

Freedom includes a fuel tank in the commercial enclosure configuration. The platform is designed for extended operation, with a 12 hour fuel tank spec on the enclosure option so you can run through long shifts or long nights without constant refueling.

Premium components, not bargain bin parts

The Freedom platform is built with commercial grade hardware throughout:

• KOEL liquid cooled 1800 RPM Tier 4F diesel engines
• Leroy Somer industrial alternators with all copper windings
• DeepSea commercial controllers
• Military grade wiring, breakers, and exhaust components
• Brushless alternator design with Class H insulation for durability in heat

This is why Freedom holds voltage, starts reliably, and stays stable when loads change.

Simple integration for automatic backup

Two wire start

Freedom supports simple two wire start integration, which makes it straightforward to pair with an ATS or control system for automatic operation. This is a big deal if your goal is “lights stay on without me doing anything,” especially during storms or when you are away.

Advanced digital controls

The all new control system is designed for usability and diagnostics, so you can monitor performance and keep the generator ready without guessing.

Choose your size: 10kW or 15kW (1 phase 120/240V)

Both models share the same core advantages: Tier 4F diesel, 1800 RPM liquid cooling, commercial enclosure, clean power, and premium controls.

• 10kW is a strong fit for essentials, smaller homes, cabins, ranch houses, and light commercial loads.
• 15kW is the move when you want more breathing room for added circuits, larger homes, heavier tools, or more comfort loads.

Not sure which one you need? A quick rule: list the loads you must run at once (not everything you own), then plan for motor starting surges and future adds.
